   1790 dnl 64-bit. The effect of this is that a 32-bit libpcap binary will not run
   1791 dnl correctly on a 64-bit kernel (the binary will use the wrong offsets into a
   1792 dnl kernel struct). This problem was solved in Linux 2.6.27. Use
   1793 dnl --disable-packet-ring whenever a 32-bit application must run on a 64-bit
   1794 dnl target host, and either the build host or the target host run Linux 2.6.26
